A thing is right when it tends to preserve the integrity, stability and beauty of the biotic community. It is wrong when it tends otherwise.
early and late responders
A. do these correlate to chemical data?
B. are there environmental conditions that describe the response?
+ constrained CCA
C. Where do these responders originate? Do they persist?
In this study, we study the impacts of amendments of both alfalfa and compost, provided at equal rates of total nitrogen, to a soil but with differing C: N ratios chosen to result in immobilization (compost) or mineralization (alfalfa). We characterize both the chemical and microbial response to these amendments and hypothesize that specific microbial communities will respond to initial nitrogen and carbon availability and that this membership will be specific to varying amendments. We expect that these distinct early microbial responders will dominate soil microbial communities in response to organic amendments and will decrease in abundance through time. Our objective was to characterize these early responding microbial communities for various organic amendments and to identify potential microbial membership within organic amendments that may be involved in plant nutrient availability.

Identified responding OTUS, used edgeR
Major phylogenetic changes detected at phylum/class levels and responding gen- era/OTUs were extracted by the likelihood ratio test after neg- ative binomial generalized linear modeling (nbGLM) of the raw counts with the false discovery rate (FDR) adjusted p-values (p-value < 0.05, R package edgeR, Robinson, McCarthy and Smyth 2010)
What is the likelihood ratio test?
